The original Halloween came out in 1978, and it's still considered one of the most impactful slasher movies ever made. Halloween tells the story of Michael Myers, a young boy who kills his teenage sister. Years later, he terrorizes the people of Haddonfield as a Boogeyman lurking in the shadows. The opening scene went down in history for putting the audience in Michael's point of view as he brutally stabs his sister to death.
